Ryan Houdek 6e46a28116 Fixes bug in syscall gettime 
gettime can have a nullptr argument and also we were using the wrong
argument

Ryan Houdek 1b4e9434e4 Add accurate std output option

Useful for terminal applications that take advantage of ncurses or
similar
 2020-03-06 07:56:02 +02:00

Ryan Houdek a858296ecd Removes SSE41, SSE42, and AVX support from CPUID 2020-03-06 07:56:01 +02:00
Scott Mansell 2babc1292c GdbServer: Breakpoint intergation 2020-03-06 07:56:01 +02:00
Scott Mansell 9a89741ff2 gdbServer: Allow continuing 2020-03-06 07:56:01 +02:00
Scott Mansell e050eace1d Refactor context start/pause/step interface 2020-03-06 07:56:01 +02:00
Scott Mansell 545b542f9b GdbServer: Implement xml target for register order 
We can now simply memcpy much of memory state.
 2020-03-06 07:56:01 +02:00
Scott Mansell e44b3ca495 Gdbserver: Implement enough to reach gdb prompt 
Memory is implemented, but without any checking or
invalidation.
Registers just hardcode a RIP for my test elf.

But GDB can read the elf over tcp, initilize and allow you to create breakpoints, which get
writen back before continue (which is not hooked up)
 2020-03-06 07:56:01 +02:00
Scott Mansell 17ffe5a7b2 GdbServer: Support a few more packets 2020-03-06 07:56:01 +02:00
Scott Mansell 23db0f66ec Add a skeleton of a GdbServer 2020-03-06 07:56:01 +02:00
Ryan Houdek e0e708a9c0 Fixes three instructions necessary for shared apps to run 
Fixes MOVHPD which was failing.
Fixes FXSTOR and FXSAVE which was accidently loading the memory location
rather than doing an LEA of the address.
 2020-03-06 07:56:01 +02:00
Ryan Houdek e9be5430b9 Adds a couple new IR ops for easy movement of registers between classes. 2020-03-06 07:56:01 +02:00
Ryan Houdek 9c873d85ec Fixes mmap syscall to work for dlopen and dlsym 
This makes my test app that is loading ld.so with dlopen actually work.
 2020-03-06 07:56:00 +02:00
Ryan Houdek af5a562508 Fixes bug in STOS and CMPS 
We were storing one too many elements. So even if the counter register
was zero it would do a store or comparison
 2020-03-06 07:56:00 +02:00
Scott Mansell 8a6efad301 Stub FNSTCW/FLDCW so libc.so.6 can be loaded 
Apparently doesn't need any other x86 instructions.
Or anything more than noped out state save/restore.
 2020-03-06 07:56:00 +02:00
Scott Mansell e9923fa704 Add lseek syscall 2020-03-06 07:56:00 +02:00
Ryan Houdek 3f06f3e87d Fixes bug in PUSH op with RSP source. 
We were modifying RSP to adjust the stack first.
Then if the source used RSP then it was offset by the store size.

`push [rsp]` was broken before this
 2020-03-06 07:56:00 +02:00
Ryan Houdek 2df55d303a Fixes bug in SHR op 
Smaller ops could have been shifting data from the larger source in to
the smaller op space when it should have been zero'd
 2020-03-06 07:55:59 +02:00
Ryan Houdek 7a4d0fbfd3 Fixes bug in 64bit def mod instructions that are in 16bit mode 
These would have been forced to 64bit when they would have wanted to be
operating in 16bit mode.
Fixes that.
 2020-03-06 07:55:59 +02:00
Ryan Houdek afdbd9ebdc Fixes issues with PSLLDQ and PSRLDQ 
These are whole vector shift instructions and they shift by bytes rather
than bits.
You only get an immediate offset for the instruction.
Implements two new IR ops to account for these instructions

This also doesn't match AArch64 behaviour 100%, requires two
instructions to emulate rather than the single one on the x86-side
 2020-03-06 07:55:59 +02:00
Ryan Houdek af6eefb495 Fixes crash in IR Interpreter that can occur with large functions 
If the tmp space grew too large and had to resize then we would have
stale pointers.
Keep around the offset instead so we don't store invalid pointers.
 2020-03-06 07:55:59 +02:00

Ryan Houdek 939e210a68 Updates SonicUtils

Ryan Houdek 9e910520c6 Adds placeholder Guest call/ret IROps 
Will be used in the future
 2020-03-06 07:55:46 +02:00

Ryan Houdek 87e6b7108f Adds an unsafe disabled flag elimination pass 
This is a very useful optimization, but may only become "safe" once we
recompile a full function.
 2020-03-06 07:55:45 +02:00
Ryan Houdek ee53b70bfe Actually enable LLVM optimization passes in the LLVM JIT 
We were using whatever was the LLVM default before.
 2020-03-06 07:55:45 +02:00
Ryan Houdek 9e132e107a Adds alignment information to the mem loadstore IR ops 
Allows us to not always emit unaligned loadstore ops for these
 2020-03-06 07:55:45 +02:00
Ryan Houdek f697da77b6 Splits up, documents, and extends the RCLE pass 
Splits this pass in to three parts.
First function is to remove StoreContext-LoadContext pairs that are
redundant. Removes the Load that has occured after a store-load pair.

Second function is to remove LoadContext instructions that are redundant
due to no other stores to that location

Third function is to remove StoreContext instructions that are redundant
due to no load happening between them (Relies on previous functions)
 2020-03-06 07:55:45 +02:00
Ryan Houdek 6dc7d2e679 Extends IR Validation to check exit to be correct 
Checks to ensure the last op in a block is EndBlock.
Checks to ensure the last instruction before that one is one of the ops
that exit correctly. So ExitFunction, Jump, CondJump, or Break.
 2020-03-06 07:55:45 +02:00
